INTRODUCTION
PRZM is a one-dimensional, finite-difference model that accounts for
pesticide and nitrogen fate in the crop root zone. PRZM3 is the most
recent version of the PRZM modeling system that links two subordinate
models--PRZM and VADOFT--in order to predict pesticide transport and
transformation down through the crop root and unsaturated zones.

Uninstalling Previous Versions of PRZM3:
Earlier versions of PRZM3 should be removed before installing version
3.12.3.
To uninstall PRZM3 version 3.12.1 or version 3.12.2 use one of the
following methods:
Execute Install_PRZM3121.EXE (or Install_PRZM3122.EXE) and follow the
instructions provided to remove the program.
or
Use the Windows Start menu to select Settings > Control Panel >
Add/Remove Programs to remove the program.
To uninstall PRZM3 version 3.12 Beta and earlier versions:
Remove versions of PRZM3 which do not appear in the Add/Remove
Programs list by manually deleting all executable files, directories,
and support files.
To install PRZM3 version 3.12.3:
The PRZM3 installation file, Install_PRZM3123.EXE, may be acquired
either from the Internet or CD-ROM. Save the installation file to a
local disk before running the installation program.
Close all applications and click on the installation program
"Install_PRZM3123.EXE". Follow the instructions presented by the
installation program.

FILE NAME AND CONTENT
After installation, the following file and directory structure should
exist in the installation directory of your local disk.
ABSTRACT.TXT - PRZM3 model system abstract.
README.TXT - PRZM3 model system execution and general support guide.
RELEASE.TXT - Summary of corrections and/or changes between release
versions.
\MANUAL - This directory contains the PRZM3 model documentation and
users' manual "PRZM-3, A Model for Predicting Pesticide
and Nitrogen Fate in the Crop Root and Unsaturated Soil
Zones: Users Manual for Release 3.12.2". This document is
in Adobe Acrobat format.
\SOURCE - This directory contains PRZM3 model executable file
(przm312.exe), source code (*.for, *.f90, *.inc) and Lahey
specific compilation and linking files. The "Libs"
subdirectory contains precompiled utility libraries having
routines necessary to link the model.
\TEST - This directory contains a PRZM3 command input file
(przm3.run), an example parameter input file
(ms1cttr-r.inp) and an installation testing script
(ptest.bat) to run the model. The "met" subdirectory
contains the test run meteorological input file and the
"output" subdirectory contains PRZM3 model output data
and control files that can be used as references in file
comparisons for the purpose of installation verification.
__________________________________________________________________________
INSTALLATION VERIFICATION
1) Run the model: from a DOS window set the default directory to \TEST.
Enter "ptest.bat". This can be accomplished from the Windows
environment by clicking on "ptest.bat" from within an Explorer
window. The model (executable located in the \SOURCE directory) will
generate several output files (38 output data and control files).
2) With the Windiff program or other suitable file comparison program,
compare the output files just generated with the like-named reference
files contained in the \OUTPUT subdirectory. If the number and
content of the files compare as identical, a successful installation
has been accomplished.
